Need CPU Help T4200 Vs T7400 Dell 1545

[D-Man]

I have a Dell 1545 with a T4200 and I also have a T7400 if I swap these would I see enough of a difference to make it worthwhile ? The Laptop has 4 Gigs of PC6400

Please give me your thoughts

I think the T7400 is definitely better with the 4MB L2 cache and slightly faster clockspeed, despite the slower FSB. If you just check emails and surf the web, it really doesn't matter. Gaming? Probably, though you're more likely limited by the GPU than CPU.

i went from a t4200 to a t6400 and saw no difference in performance.

Minimal (5% maybe due to cache) difference that likely won't be felt in real world apps at all: http://www.cpubenchmark.net/cpu_list.php
